APPARATUS FOR CEMENTIN G SG'LES T0 SHOE UPPERS.

Application tiled December 1,8, 1926. Serial No. 155,584.

Thisjinvention relates to apparatus for cementing soles to the upper leather of shoes and is designed to produce a press structure which can be used for half-soling two shoes at a time, and for whole-soling or half soling a single shoe with equal facility. To this 'end the apparatus consists essentially of a proper. pad of generally rectangular shape, one or t-wo presses movable l0 lengthwise over said pad and means for preventing the bulging upward of that port-ion of the pad not acted on by one of the presses if the other is not being used. The best forms of apparatus at present known to me embodying my invention are illustrated in the accompanying three sheets of drawings in which:

Fig. l is a side elevation of a machine for operating on high heeled shoes. i

Fig. 2 is a similar View of a iiiodiezitioii adapted to half-sole either high heeled or flat heeled shoes, and shown half-soling one of the latter.

Fig.3 is a similar view showing the operation of whole soling.

Fig. 4 is an end elevation of Fig. 3.

Fig. 5 is a side elevation showingr another modification.

Fig. 6 is a vertical section on line 6 6 of "1 Fig. 5, and I Figs. 7 and 7 are perspective views ot one type of apparatus.

Fig. 8 shows a modified forni of retarding plate.

'Throughout the drawings like reference characters indicate like parts.. l represents generally the bed of the machine which has al downwardly bent portion l adapted to receive and retain a .small quantity ol' tluid such as glyceriiie, water or air` when the depression formed by it is covered and enclosed liv fluid-tight, dia|ihragiii 'z2 of rubber generally covered by a fai-ing of leather il as shown iii Fig. (i. This diaphragm is held down on the bed of the machine and foiiiis an airtight joint therewith through the. agency of the clamping fiaiiii` which is bolted to the' bed as shown iii Fig. .\ii .outletf cock 4i, and an inlet connection 7, each controlled by :i valve. are Ishownun Figs. il, 4 and 5, by niiii'iiliulriliou of which the( quantity of fluid confined beneath the. diaphragm 2 can be. controlled. rlhc parts so far described cooperate to foi-iii a tluid supported pad which is the preferred form of pad element employed in my invention although in some lcases' pads of other construction might be substituted.

The pad so formed is preferably generally rectangular in outline and the sides of the hed sustaining it are provided with longitudinally extending ribs on which slide one or more press housings 7. 7 by iiieans ot' grooved feet 8, 8a engaging said ribs. 9. 9" represent generally screws mounted in said press housings and adapted to torce downward specially constructed lasts 1S. 1X which fit inside of shoes 19. 19 or Q0, which are to be half soled or Whole soled as the occassion may require.

lVhen the operator is half-soliiig. two shoes may be operated on at once as shown in Fig. l by means'of the two presses there shown. If whole-soling is to be done only one shoe can be operated on at a time as shown at 20 in Fig. 3. one of the presses then being removed and the other one moved over into mid-position on the bed l.

It is evident that in the half-soling operation only a portion of the pad is covered by one shoe and that, if the pad is of the liquid supported variety, the uncovered portion of tli'e diaphragm will bulge upward under the thiid pressure, and that time will be wasted i in forcing down the shoe (as I9) any additional dist-ancc to take up the play in the diaphragm thus permitted before the necessary degree of resisting pressure is encountered for the cementing operation. Alsoithis excessive depression of the one shoe may produce such a distortion of the diaphragm that the operation will notv be entirely successful. The use of another press in which the other shoe 10L can be operated on at the saine time overcomes this ditliculty, each shoe acting as a. retarding device to prevent the bulging up of the diaiilirz'igni which would otherwise be produced by the pressure of the other shoe.

Ln lsonic cases the operator may desire to half-sole a` single shoe and in that case l substitute l'or the other shoe and its press a' -pecial diaphragm .retaining device which may he of the t`orii'i1 shown in Fig. 2, coinpi'isiiig a smaller housing l2 in which the screw and hand wheel ll-22 are mounted to press upon a plate such as l0 shown in Figs. t and T. This plate has a thicker, reenforeed portion 10'1 on which the screw l1 bears. The `screw ll renders the retarding to the left out of o eration when the Vpress is moved to the mi die osition for wholesoling. This is indicate in dotted lines in Fig. 5. In all cases the housings'12 or 13 slide along the. ribs 6.

At 'least one end of the bed-2 should be raised as shown at 16 in Fig. 2 lo support high heeled shoes in half-sol-ing. A retarding plate shaped to hookover such a raised end is shown at 23 in Fig.. 8; The other end stituted for drawings, y Amongtlie 'edvantagesof the Invention.

17 may be shaped to cooperatewith' flat .heeled shoes as shown inJFigs. 2 and Iif the operator has enough Work to kee two 'presses going, each may have a bed s iaped at each end to support high heeled shoes in one case, and flat heeled shoes in the other case. Thus in Fig. 1, the two bed ends 16 and 16t are both shaped to support high heeled shoes for'half-soling while/in Figs. 2. 3, 5 and 7, one end of the bed is for highheeled shoes and thc other for llat heeled shoes. .The screw 1l on the diaphragm retainingy apparatus may be simp y used for adjustment thereof, having a knurled head 21 as shown in Fig: 7, orit may be-used for operating the press in place of the screw .'9 if it is given a hand wheelr22 as' show-n inFig. 2 or other means by which Ya considerable degree of pressure can be applied to the fluid supported pad through the plate l0. In this mode of vuse the sere-w 9-in the main press bearing on the last -18 willrbe adjusted for operating on shoes having soles. of a given thickness and then lhe'handwl'ieel screw 11--22 will behacked olf te permit the .shoe and last to he inserted in position and then said. hand wheel will be( 'revolved .and-

plate 10 forced down to create `the necessary pressure under` the shoe. A fter the cementing h'asbeen completed, tl1c 'hand wheel screw 11-..-22 will be barkcdolf again for releasing the shoe and last. so they can be removed vand new ones inserted and the operation again-repeated, ln thesame way infoperating the double press structure ot Fig. l it is usually necessary to operate only one of thepress screws. 5) or 9, the withdrawal-of pressure fromtthe fluid under the diaphragmpennitting both shoes to be re-` moved., Other forms of laslsimay be sub- Vthe special forms shown in the 1.
